Renewable energy stakeholders are well aware that clean energy is slowly but steadily transforming the energy landscape and that message couldn’t have been more clear at the recently concluded Power-Gen International, the largest show for the traditional power generation industry. Since all forms of power generation are represented at the show through the four co-located conferences, PennWell calls the second week in December "Power Generation Week."

One of Europe's largest utilities is on the cusp of reportedly transforming its business from being a centralised energy provider into a decentralized energy provider.

Reliance Industries Limited (RIL) and US global conglomerate GE on Thursday announced a global partnership in the Industrial Internet of Things (IIoT) space to boost digital transformation.

This paper presents a framework for measuring the digital transformation of manufacturing industries, and maps the impact of digital technologies across these several dimensions: firm productivity growth, business dynamism, industry concentration, firm mark-ups and mergers and acquisition activity.

This report provides an assessment of G20 economies’ performance with respect to digitalisation and examines some of the most pressing policy challenges in areas spanning from access to digital infrastructures to digital security to legal frameworks. It includes a set of 11 core policy recommendations that could underpin a comprehensive G20 digital agenda.

At the OECD, ee have started an ambitious 2-year project to examine how the digital transformation affects policy making across the broadest possible range of fields and topics. The objective is to work with governments, business, labour and civil society to develop policies to harness the power of the digital revolution for OECD members and developing countries and unlock the benefits for everyone.

How immigrants contribute to developing countries’ economies shows that negative perceptions are often unjustified. It points out that immigrants are no burden on the economies of host countries, and that in developing countries, their impact on labour markets, economic growth and public finance is generally positive although relatively limited.

As the Millennium Development Goals (MDGs) approach their expiry date, we must focus our efforts on ensuring a brighter, more inclusive and sustainable future for all. We face a plethora of common issues: growing inequalities; changing consumption patterns and population dynamics; increasing natural resource scarcity; and ongoing illicit financial flows.

This report aims to help environmental and other competent authorities in OECD countries to promote green business practices among small and medium-sized enterprises (SMEs). It analyses different ways to establish environmental regulatory requirements for facilities with low environmental risk (most of which are SMEs).

Despite people’s perceptions of us, we economists are neither futurologists, nor historians. But we do see trends that we try to interpret, by applying objectivity where subjectivity abounds, and using the (rather few) tools we have developed to address (very many) major social problems.

How Africa urbanises will be critical to the continent’s future growth and development, says the African Economic Outlook 2016 released today at the African Development Bank Group’s 51st Annual Meetings.

The photovoltaic perovskite, methyl­ammonium lead triiodide [CH3NH3PbI3 (MAPbI3)], is one of the most efficient materials for solar energy conversion. Various kinds of chemical and physical modifications have been applied to MAPbI3 towards better understanding of the relation between composition, structure, electronic properties and energy conversion efficiency of this material. Pressure is a particularly useful tool, as it can substantially reduce the interatomic spacing in this relatively soft material and cause significant modifications to the electronic structure. Application of high pressure induces changes in the crystal symmetry up to a threshold level above which it leads to amorphization. Here, a detailed structural study of MAPbI3 at high hydro­static pressures using Ne and Ar as pressure transmitting media is reported. Single-crystal X-ray diffraction experiments with synchrotron radiation at room temperature in the 0–20 GPa pressure range show that atoms of both gaseous media, Ne and Ar, are gradually incorporated into MAPbI3, thus leading to marked structural changes of the material. Specifically, Ne stabilizes the high-pressure phase of NexMAPbI3 and prevents amorphization up to 20 GPa. After releasing the pressure, the crystal has the composition of Ne0.97MAPbI3, which remains stable under ambient conditions. In contrast, above 2.4 GPa, Ar accelerates an irreversible amorphization. The distinct impacts of Ne and Ar are attributed to differences in their chemical reactivity under pressure inside the restricted space between the PbI6 octahedra.

In this work, the mechanism of solvent-mediated desolvation transformation of lenvatinib mesylate (LM) was investigated. Two new solid forms of LM, a dimethyl sulfoxide (DMSO) solvate and an unsolvated form defined as form D, were discovered and characterized using powder X-ray diffraction, thermogravimetric analysis, differential scanning calorimetry, polarized light microscopy and Raman spectroscopy. To investigate the thermodynamic mechanism of solvent-mediated desolvation transformation (SMDT) from LM DMSO solvate to form D, solubilities of LM DMSO solvate and form D in binary solvent mixtures of DMSO and water at different water volume fractions and temperatures (293.15–323.15 K) were measured and correlated by non-random two liquids model. The solubility data were used to evaluate the thermodynamic driving force of the SMDT process from DMSO solvate to form D and the effect of the activities of water and DMSO on the transformation process. Raman spectroscopy was used to monitor in situ the solid phase compositions during the SMDT process from LM DMSO solvate to form D while the solution concentration was measured by the gravimetric method. The overall desolvation transformation experiments demonstrated that the SMDT process was controlled by the nucleation and growth of form D. Moreover, effects of operating factors on the SMDT process were studied and the results illustrated that water activity in solution was the paramount parameter in the SMDT process. Finally, a new SMDT mechanism was suggested and discussed.

The solvent-mediated desolvation process of newly discovered lenvatinib DMSO solvate to form II at different water volume fractions and temperatures was investigated. It is confirmed that the activity of water is the most important factor affecting the desolvation process: the desolvation process only occurs when the activity of water is greater than the activity of DMSO, and one new mechanism of solvent-mediated desolvation process was proposed.

A new polymorph (form II) is reported for the 1:1 dimethyl sulfoxide solvate of 2,3,5,6-tetra­fluoro-1,4-di­iodo­benzene (TFDIB·DMSO or C6F4I2·C2H6SO). The structure is similar to that of a previously reported polymorph (form I) [Britton (2003). Acta Cryst. E59, o1332–o1333], containing layers of TFDIB mol­ecules with DMSO mol­ecules between, accepting I⋯O halogen bonds from two TFDIB mol­ecules. Re-examination of form I over the temperature range 300–120 K shows that it undergoes a phase transformation around 220 K, where the DMSO mol­ecules undergo re-orientation and become ordered. The unit cell expands by ca 0.5 Å along the c axis and contracts by ca 1.0 Å along the a axis, and the space-group symmetry is reduced from Pnma to P212121. Refinement of form I against data collected at 220 K captures the (average) structure of the crystal prior to the phase transformation, with the DMSO mol­ecules showing four distinct disorder com­ponents, corresponding to an overlay of the 297 and 120 K structures. Assessment of the inter­molecular inter­action energies using the PIXEL method indicates that the various orientations of the DMSO mol­ecules have very similar total inter­action energies with the molecules of the TFDIB framework. The phase transformation is driven by inter­actions between DMSO mol­ecules, whereby re-orientation at lower temperature yields significantly closer and more stabilizing inter­actions between neighbouring DMSO mol­ecules, which lock in an ordered arrangement along the shortened a axis.

Nurses roles, responsibilities, and education should change significantly to meet the increased demand for care that will be created by health care reform and to advance improvements in Americas increasingly complex health system, says a new report from the Institute of Medicine.
